Title: "A survey on incentives and reputation management on D2D
ecosystems"
by
Mr. Dimitrios CHATZOPOULOS
Abstract:
Advances in device-to-device (D2D) ecosystems have brought on mobile
applications that utilise nearby mobile devices in order to improve users'
quality of experience (QoE). The interactions between the mobile devices
have to be transparent to the end users and can be of many services -
opportunistic networking, traffic offloading, computation offloading,
cooperative streaming and P2P based k-anonymity location privacy service,
to name a few. Whenever mobile users are willing to ``ask for help'' from
their neighbours, they need to make non trivial decisions in their
selections in order to maximise their utility. Current motivation
approaches for mobile users that participate in such environments are of
two types: (i) credit-based and (ii) reputation-based. These approaches
rely either on centralised authorities or require prohibitively many
messages or require tamper resistant security modules. In this survey we
present (i) the characteristics of D2D ecosystems and the features of D2D
applications and frameworks and (ii) the existing types of cooperation
enforcing and incentive mechanisms and their requirements to be
operational. Next, we discuss (i) a decentralised cryptocurrency that can
be used to support the bookkeeping of a cooperation enforcing mechanism
and (ii) the multiway trade-off between consistency, operational costs, in
terms of messages exchanged and storage needs, and awareness in
reputation-based cooperation enforcing mechanisms.
